> The article says that manufacturers are not allowed to list sesame as an ingredient unless it actually is an ingredient.
Correct. I wasn't suggesting adding it to the ingredients list.
> The law says they can't warn about potential sesame contamination.
The law does not say that. It says that manufacturers can't do that instead of following standard cleaning practices.
> Instead it must either be an actual ingredient or manufacturers must clean the equipment.
Yes, they
must clean the equipment. None of this is new stuff, this has been the case for many years.
Why is it suddenly too much of a burden for food manufacturers to clean their equipment? Is wanting to avoid cleaning not a huge red flag about that manufacturer?
> I'm guessing this isn't a question of a small amount of profit loss; it's probably a big expensive deal to comply with this law.
Knowing large corporations, I'm guessing that the economics of it aren't the real issue at all. If it costs substantially more, they'd just add a few cents to the cost of the food.
